Nov 9, 2010

My squid Configurtion is below. Is there any need to tune the system parameters Like from 'SYSCTL.conf' for better diskd performence or another problem. at this time i am using default system parameters. Please help me in detail what is the reason of squid slow performence if there ia a need of any system tuning please tell me in detail.

I've just noticed that unrar is suddenly taking minutes to extract instead of seconds.
I can remember if its recently been updated, but I've uninstalled and reinstalled it and the version is: unrar.x86_64 0:3.7.8-3.fc10
I've found a few Ubuntu posts about it on Google, but in true Ubuntu fashion nobody has any answers!
What's odd is that when I unrar a file from (Nautilus or "unrar x *.rar") it takes say 4mins, then if I do it again it takes 15secs, like as if its caching somewhere.

So I just reinstalled OpenSUSE 11.2 and I went from having 20-30 mbps speed to and from my 1 tb usb ntfs external hard drive to having about 1 mbps transfer speeds now. Is there any suggestions for how I can fix this? I know it can go faster, I just need to figure out how. and would setting acpi=off at boot affect this?
Opensuse 11.2
KDE 4.3
64 bit
EXT4 main disk
NTFS external
fdisk -l code...

My problem is extremely slow write on hard disk and 100% cpu usage and it happens when I want to write something on the hard derive not any other external derive.
Tried a fresh ubuntu install. No change. I am not even sure if it is a software or hardware problem.

I've been using squid-cache for a long time for authentication/authorization. It has work fine for years, but now it starts working too slow only in one computer (the others, works fine).
It's configured as a reverse proxy.
I see it can be a DNS problem, but the computer is configured with the same dns servers in resolv.conf that the other computers have.
I use squid 2.6.stable14 on RHEL 4.4.
If I restart the service (service squid restart) it works fine, but 15-20 minutes later, the problem repeats.

Slow access to web site using squid and Internet explorer.I am trying to troubleshoot an issue I am stuck on. We have a website that is loading .htm documents extremely slow when using Internet Explorer 8 behind Squid. When we bypass the proxy and go directly out to the internet all is fast and pages load fine.But when the proxy is on documents will take sometimes up to 6 minutes to load.This issue is only apparent using Internet explorer 8.I do not see the issue when using firefox with Squid.I have tried to use the no_cache directive thinking it may have been the cache but that didn't work either.I am attaching our access.log, store.log and squid.conf.

I have configured a squid proxy server with @2 eth in different network subnet and with site blocking and extn file download blocking. One eth0 for office wired network and another eth1 is for office wireless network for laptop use for guest and visitors.
The problem is [URL] is an Indian government website, which is not working though this proxy server and the Internet Explorer is getting very slow and freezing the computer. In alternate I have configured a another test server with squid proxy with out any security and test the same. the problem is still with the all the computer in the network. The above website is perfectly working with Gateway configuration in TCP/IP properties in Network Configuration in MS Windows XP computers but through squid proxy its not working.

I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port 172.16.31.1:3128 transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet

I have been working in Linux for the past two years.And working in squid for the past 6 months.The following is my Setup
ETH1 - ISP1 (Active)
ETH2 - LAN (Active)
ETH3 - ISP2 (Inactive)
Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.

I'm having trouble with my database server run with PHP & MYSQL; i just installed this system on a SUSE Linux Enterprise Sever; the Server its self is an HP Proliant ML370G with 4GB RAM
The system was fine for like 3 weeks until recently when it started slowing down. Apparently, eveything is normal when you are accessing the server, for example when you are browsing on the database web interface; but problem is when you start working in the database, when you try submitting into the database, its really slow on processing, i have to first restart the mysql;
Could it be RAM? or the SQL itself?

When I'm trying to login to the ftp server with appropriate username and password its taking almost 10-15 seconds to authenticate making the login process slow, even when I'm uploading files its again hanging for 10-15 seconds before completing the job successfully.
Its not like its happening every time, but 7 times out of 10.
Any idea how can make the authentication fast?

I have an Ubuntu Server 10.10 install on a VIA C7 chip. It seems to pause for about 5 min on a USB component.
It is a fresh install, here is a snip from my messages log code...
My KB is USB, so I would rather not disable it if at all possible. The next time I can take it down, I will test disabling it though...

I've been having a problem in Ubuntu 9.10 recently where starting about 2 minutes after startup my computer slows down and becomes unresponsive. I believe the problem is associated with a high IOWait because I have the system monitor applet on my Gnome Panel and it displays 100% IOWait every time my system starts to slow down.
I have tried booting into other kernel version and the problem persists. I don't really know what IOWait is or how to diagnose this problem further. I've looked around online and it seems like you have to find a specific process that is causing the IOWait, but I don't understand how to go about doing that.

I've been using Ubuntu consistently for about three days now. I really, really love the interface and how everything works and all that, but I've been having a couple of weird problems with speed.
Graphics things seem to work really well. When I go into the overview of all my workspaces, it's instant and looks great. The problem is when I open and use some applications.
For example, when I open up the software center, it takes longer than it did the first time to start up. Also, when I drag windows off from being maximized, it takes literally about five seconds for it to show up as being dragged around by my mouse.
When I look at the system monitor, about 20% of my CPU cores are constantly being used. That's 20% each. I have a 3-core CPU, could that be the problem?
Another example: when I went to ..... just now, it would take a second for any volume changes in the video to register.
And I also have smooth scrolling in firefox, but it's very unresponsive now. It's slow as all hell. Even notifications are showing up more slowly.
So, what's the deal? What could I have done wrong?
CPU: AMD Phenom II X3 2.8Ghz
GPU: ATI Radeon HD 4860 1gb
RAM: 4gb
One more thing: I have really bad screen tearing when I try to move windows around, as if there isn't any vsync on. Where can I turn it on or fix this?
I'm still pretty new to Ubuntu and Linux, but I'm an advanced computer user. Since I feel linux is killing my CPU I think I'm going to boot back into Windows 7 for now, but if I can fix this problem I think I want to keep Ubuntu as my main OS after this, having Windows for games, unless I can get Wine to work right with them.

I'm having issues playing HD videos ( some with 720p level, much more apparent with 1080p level one) The video appears to slow then becomes choppy, becoming de synced from the audio that carries on as normal. This occurs with both VLC player and XBMC, though the latter is better. My specs: Fedora 12 3.2 Ghz P4 processor 1Gig ram Radeon 9800 xt gfx card (I couldn't get the 9.3 ati driver to work)

I was browsing my folder with lots of images, after finished i close nautilus and i notice that my computer became slow, so i'll check it with system monitor and had found that nautilus are using almost 100mb of ram (opening 4 tabs). I'm not sure if this was normal or not because i try to reopen the same folder with pcmanfm and it only consumes less than 20mb of ram (opening 4 tabs).
here's the screenshot from system monitor .

I have squid running on F12 fully updated. Pretty much stock config except bigger cache size.
Over time it seems to start lagging and occupying more memory. Currently using ~400Mb after a couple of months. I'm sure its causing some lag / refreshes because if I turn if off and go direct to internet the same site I had to hit refresh on, loads instantly.
Going through the logs in /var/log/squid I don't see anything suspicious with the untrained eye, whats a better way of debugging it to see where/why the delays are happening? Its a single user setup (for fun really lol) so theres a lot of misses in access.log. cache.log just has a handful of bad img headers which does not line up with lagging websites.code...

Motherboard: Asus P5KPL-CM
Audio Chipset: VIA VT1708B
No linux sound drivers on Asus' site. No ubuntu 9.10 drivers on VIA site. Low sound with default drivers. I've edited /etc/modprobe.d/alsa-base.conf with options snd-hda-intel model=3stack, but no luck. I actually had to do a sudo sh then edit it that way with vi because it was read only. Didn't do anything.

I just built my first computer from the ground up and installed linux x86_64, FC10, and among other problems, i cannot get the volume of my speakers to play much above a low volume. i have the pulseaudio volume control set to 100% for the output and input levels. i adjust all my video and audio players volumes to the max also, but the volume from the speakers is still very low. the speakers worked fine with my old hp computer. is there anything i can do, adjust to fix this?

I just set up squid for the first time. I have zero experience with proxy servers. I used this guide:[URL](I also looked at a few other guides such as this one:ttp://ubuntuforums.org/showthread.php?t=320733. However, I wanted to most barebones config to start with and the link I used was the simplest.)So now that I have it set up, I'm testing it with FoxyProxy. It is not working well. I went to speedtest.net. The download and ping tests were just as fast as without the proxy, but the upload test fails completely.Furthermore, many web pages load very slowly or not at all. So performance is very mixed, but mostly poor.
